Please refer to FIG. 1 to FIG. 5 . FIG. 1 is a schematic diagram of astroller 1 according to an embodiment of the present invention. FIG. 2and FIG. 3 are lateral view diagrams of the stroller 1 in differentstates according to the embodiment of the present invention. FIG. 4 andFIG. 5 are partial diagrams of the stroller 1 at different viewsaccording to the embodiment of the present invention. As shown in FIG. 1to FIG. 5 , the stroller 1 includes a frame 11 and a basket 12 disposedon the frame 11. The basket 12 includes two tube mounts 121, a firsttube member 122, a second tube member 123 and a basket covering 124. Thetwo tube mounts 121 are disposed on the frame 11 and located at twolateral sides of the frame 11. The first tube member 122 is connected tothe two tube mounts 121. The second tube member 123 is rotatablyconnected to the two tube mounts 121 and switchable relative to theframe 11 between an unfolded position as shown in FIG. 2 and a foldedposition as shown in FIG. 3 . The basket covering 124 is disposed on thefirst tube member 122 and the second tube member 123. A storage space isenclosed by the basket covering 124, and a volume of the storage spaceis adjustable by rotation of the second tube member 123 relative to theframe 11. When the second tube member 123 is rotated from the foldedposition as shown in FIG. 3 to the unfolded position as shown in FIG. 2, the basket covering 124 is gradually expanded, so that the volume ofthe storage space enclosed by the basket covering 124 is increased. Whenthe second tube member 123 is rotated from the unfolded position asshown in FIG. 2 to the folded position as shown in FIG. 3 , the basketcovering 124 is gradually collapsed, so that the volume of the storagespace enclosed by the basket covering 124 is decreased. However, thenumber of the tube mount is not limited to this embodiment. For example,in another embodiment, there can be only one tube mount located at oneside of the frame.

Please refer to FIG. 1 to FIG. 10 . FIG. 6 is a partial diagram of thebasket 12 according to the embodiment of the present invention. FIG. 7is a partial exploded diagram of the basket 12 according to theembodiment of the present invention. FIG. 8 is a partial internalstructural diagram of the basket 12 according to the embodiment of thepresent invention. FIG. 9 and FIG. 10 are partial internal structuraldiagrams of the basket 12 in different states according to theembodiment of the present invention. As shown in FIG. 1 to FIG. 10 , thetwo tube mounts 121 located at the two lateral sides of the frame 11 canhave the same structure. The tube mount 121 at one lateral side of theframe 11 is introduced as follows for simplicity. The tube mount 121includes a first mount member 1211 and a second mount member 1212. Thefirst mount member 1211 is disposed on the frame 11 and connected to thefirst tube member 122. The second mount member 1212 is disposed on thesecond tube member 123 and rotatably combined with the first mountmember 1211. The second tube member 123 is rotatable relative to theframe 11 by rotation of the second mount member 1212 relative to thefirst mount member 1211.

Furthermore, the first mount member 1211 includes a housing 1211A. Thesecond mount member 1212 includes a hub 1212A rotatably combined withthe housing 1211A. A plurality of first ribs 1211B is formed on at leastone portion of an inner wall of the housing 1211A. A plurality of secondribs 1212B is formed on at least one portion of an outer wall of the hub1212A. The first mount member 1211 and the second mount member 1212engage with each other by the plurality of first ribs 1211B and theplurality of second ribs 1212B for positioning the second tube member123 at a desired position between the folded position and the unfoldedposition. In other words, the second tube member 123 can be positionedat any position between the unfolded position and the folded position bypositioning the second mount member 1212 relative to the first mountmember 1211 with engagement of the plurality of first ribs 1211B and theplurality of the second ribs 1212B, which achieves a purpose ofmultistage adjustment of the volume of the storage space.

Preferably, in this embodiment, the plurality of first ribs 1211B can beformed around at least one portion of the inner wall of the housing1211A and made of plastic material, and the plurality of second ribs1212B can be formed around at least one portion of the outer wall of thehub 1212A and made of plastic material. Furthermore, a cross section ofeach of the plurality of first rib 1211B and a cross section of each ofthe plurality of second rib 1212B can be formed in arc shapes. In such away, the first ribs 1211B and the second ribs 1212B can be forced to beelastically deflected to disengage from each other for allowing therotation of the second mount member 1212 relative to the first mountmember 1211 when the second tube member 123 is operated by a user.Besides, the first ribs 1211B and the second ribs 1212B can beelastically recovered to engage with each other for positioning thesecond mount member 1212 relative to the first mount member 1211 whenthe second tube member 123 is released by the user. Therefore, noadditional releasing mechanism for disengaging the first ribs from thesecond ribs is required, which simplifies operation and bringsconvenience in use.

Please further refer to FIG. 1 to FIG. 5 . In order for easy storage andtransportation of the stroller 1, the frame 11 is foldable and includesa handle 111, a front foot 112, a rear foot 113 and a seat 114 installedon the handle 111. The first mount member 1211 of the tube mount 121 isdisposed on the front foot 112, and the tube mount 121 further includesa third mount member 1213 disposed on the rear foot 113 and rotatablycombined with the first mount member 1211 and the handle 113. In otherwords, the front foot 112 is rotatably connected to the rear foot 113 bythe two tube mounts 121, and the handle 111 is rotatably connected tothe rear foot 113 by the two tube mounts 121.

In addition, in order to facilitate folding operation of the frame 11,the frame 11 further includes two link members 115. Each link member 115is movably connected to the handle 111 and the first mount member 1211of the corresponding tube mount 121. The handle 111 drives the frontfoot 112 to rotate toward the rear foot 113 by the two link members 115when the handle 111 rotates relative to the third mount member 1213 tomove toward the rear foot 113. However, the present invention is notlimited to this embodiment. For example, in another embodiment, therecan be no link member or only one link member located at one lateralside. Alternatively, there can be no third mount member, and the handlecan be directly pivoted to the front foot or the rear foot accordingly.

In contrast to the prior art, the present invention utilizes theplurality of first ribs on the first mount member and the plurality ofsecond ribs on the second mount member which are preferably made of theplastic material, to allow or restrain rotating movement of the secondmount member relative to the first mount member. Therefore, the secondtube member can be positioned at any position between the unfoldedposition and the folded position by positioning the second mount memberrelative to the first mount member with engagement of the plurality offirst ribs and the plurality of the second ribs, which achieves apurpose of a multistage adjustment of the volume of the storage space.Furthermore, the plurality of first ribs and the plurality of secondribs can be forced to be elastically deflected to disengage from eachother for allowing the rotating movement of the second mount memberrelative to the first mount member when the second tube member isoperated to rotate relative to the frame.

Those skilled in the art will readily observe that numerousmodifications and alterations of the device and method may be made whileretaining the teachings of the invention. Accordingly, the abovedisclosure should be construed as limited only by the metes and boundsof the appended claims.
